In this study, rice husk (RH) was modified by HCl and HNO3, and the activated RHs were used as adsorbents for removal of UO22+ ions from aqueous solutions through batch equilibrium technique. Materials and methods: The influence of pH, equilibrium time,temperature, adsorbent dosage, and initial uranium concentration on adsorption percent was investigated. Results: Obtained results declaredthat the pH of aqueous solutions had affected UO22+ ions removal, which was indicated by the increased removal efficiency with increasingsolution pH till pH 3. Conclusion: Experimental data were verified with Langmuir and other isotherms and were found to be well fitting withLangmuir isotherm models. A feasibility study for the whole process was performed.
